Abstract: ABSTRACT A rotary shear machine is described having a plurality of oppositely rotating hollow cylinder pairs carrying helical blades for transversely shearing several continuously moving webs perpendicular to their directions of travel.  Each cylinder pair includes a separate reversible DC motor drive and an electronic digital control system regulating the motor drive for cutting sheets of predetermined lengths from the respective webs. A unique feature of the machine 15 a web feed and pull roller system having an independent drive for engaging and feeding the continuously moving webs into the respective helical blade shears and pulling sheets from the respective shears as they are cut from the continuously moving webs.  The upstream feed roller system includes means for sensing web velocity and gen-erating electronic pulses for input into the control means regulating the respective reversible DC motor drives driving the respective helical blade shears.  The feed roller system further includes means for continuously gen-erating electronic pulses even though the velocity sensing component is not in contact with the moving web.  The proximity of the web velocity sensing means to the helical blade shears enables the helical blades to sever sheets from the respective webs with a high degree of precision and uniformity.

Abstract: Abstract of the Disclosure The specification discloses a twin baking oven having two ovens located one above the other in a common housing.         The controls for the ovens are located in the upper part of the housing above the upper oven.  Air ducts are pro-vided between the ovens and the housing in order to draw in cool air at the bottom of the housing and to exhaust it at the top.  In order to protect the oven controls from overheating, the lower oven is thermally shielded by means of shielding plates from the cooling air ducts and the cooling air passes around the controls before being ex-hausted from the housing.   The upper oven is preferably a microwave oven.  In this way electrical or electronic control may be used for the oven without being subjected to damage by heat.

Abstract: ?????     ABSTRACT            Circuit device for checking the closed position of a folding door In the case of prison cell doors, strong room doors and the doors of safes and strongboxes the problem exists of protecting a switch fitted to the door or its frame and which as a result of the closing movement of the door releases an alarm signal from manipulations by unauth-orised persons, for example the emission of a false signal by a prisoner when the cell door is open.     A signal switch     with roller      is detachably fixed to door and a stationary eccentric disc     which serves as the switch actuator is detachably fixed to frame    .    This mechanical switch device            is housed in a casing , whose base     is welded to door     and whose cover-like cap     is locked from the inside to casing base by means of a cylindrical lock     in casing     and is consequently secured against raising therefrom.    In the case of an optical switching device a transmitter for infrared alternating light      and a receiver      with switching transistor      are arranged within the door or frame     or vice versa.    Only when the door     is closed is an infrared beam      passed through two aligned transmission beam ports     in door and frame to receiver     , thereby releasing an alarm signal.

Abstract: HYDROCYCLONE     UNDERFLOW DENSITY CONTROL               Abstract of the Disclosure Hydrocyclone apparatus having means for con-trolling the gravity of the discharging underflow which consists of a device formed of resilient material that is mounted directly below the apex opening of the hydro-cyclone.  The device provides a plurality of sectors which when relaxed extend inwardly toward the hydrocyclone axis, with the side edges of each sector in juxtaposition with adjacent sectors. When the hydrocyclone is operating, the downward thrust of underflow material directly over-lying the device causes the sectors to be deflected downwardly to so control the underflow as to maintain its density substantially constant irrespective of changes in the density of the slurry supplied to the inlet. Prefer-ably the construction of the device is such that when the sectors are relaxed they are arched upwardly.

Abstract: ABSTRACT OF THE DISCLOSURE    A starting aid for a combustion engine comprises a hollow elongated body and a refractory electrical heating element mounted in the body at one end thereof.   Formed in said one end of the body are one or more holes through which, in use, the heating element can be exposed to the combustion mixture of an engine.          In addition, the body is formed with at least one exhaust aperture which is spaced from the heating element in the direction of the other end of the body and which permits the escape of gases entering the body through said one of more holes.   Extending through the body and electrically connected to the heating element is an electrode rod for supplying heating current to the heating element to raise its temperature.   The electrode rod includes two relatively movable parts which are mechanically connected by resilient means to maintain the heating element in compression against said one end of the body and which are electrically connected by a flexible braid.   A heat resistant, gas restricting packing layer is mounted between the body and the electrode rod intermediate the ends of the body to allow free axial movement between the electrode rod and the body and substantially prevent gas flow past the packing layer.
